LED Contact Lenses

Researchers at the University of Washington have apparently created the prototype for a contact lens with a built in LED display. An array of red light emitting diodes no more that 1/3 of a millimeter thick and an electronic circuit are contained in the prototype contact lens. There is no power source contained in the lens as yet so the diodes don’t light up, but a operational prototype isn’t too far off according to scientists. The device could theoretically be powered by a combination of solar cells and radio frequency power. The applications of a fully functional high resolution display are almost limitless. It may be a while till the full potential of this technology is reached, but in the meantime it’s certain fun to imagine all the possibilities this technology has to offer.
